Etabs Mass Summary By Story Better [upd] • Working

The ETABS mass summary by story output provides a detailed breakdown of the mass components for each story in the building. The output typically includes:

For Modal Analysis, the distribution of mass per story dictates the mode shapes and natural periods of the structure. Using story-based summaries allows engineers to easily calculate the for each level. This is critical for identifying whether the structure is prone to torsional irregularities. By viewing mass through the lens of individual stories, engineers can better understand how specific levels contribute to the overall dynamic response, leading to more targeted optimizations in stiffening or softening the frame.
